For coastal Florida homes, Sherwin-Williams Duration and SuperPaint exterior lines provide the best balance of salt-air resistance, UV stability, and mildew protection. Grove Street Painting includes rust-inhibitive primers on metal and trim sealing on every exterior project, and our Sarasota exterior painting scope sets the primer and finish coat for each surface before the price is written.
Coastal Florida exteriors face three accelerated degradation factors: salt air corrosion, intense year-round UV radiation, and high humidity that promotes mildew growth. The coating has to be chosen for those three conditions, which is why the written proposal names the product going on your home.
No two coastal Florida houses age the same way. A house under oak canopy holds more mildew on its shaded north wall, while a house on an open lot takes more direct salt and UV on every elevation. That is why the walkthrough comes before the product list: it is where the attention goes to the walls that actually show the wear, instead of treating every side of the building the same.
Product selection varies by substrate. Stucco gets elastomeric coatings that bridge hairline cracks. Wood trim gets alkyd-modified primers for maximum adhesion. Concrete block gets masonry-specific primers. See our full exterior painting process with product specifications for each surface type.
